While speaking at the Television Critics Association's winter press tour, the 42-year-old actor said: 'The only manner in which the cast has discussed wrapping [The Big Bang Theory] has been that we’re all going to be very sad when that day comes. But I think at this point everyone’s very comfortable with 12 seasons being a good time to go home and see our families.'
The show was renewed for season 12 in March last year.
Galecki stars alongside Kaley Cuoco, Jim Parsons, Simon Helberg, Kunal Nayyar, Melissa Rauch and Blossom alum Mayim Bialik.
